hard disk detection failure

[SiaMeX]

hi...
I cannot detect my HDD. That often happens (but not always) when i use my pc usually at night time. The first time it happened was when i moved in to other apartment. One thing i noticed, when we moved in, is that my monitor display was not as quite as good as before. I think it was just on voltage supply problem on my new appartment. And the reason why i can't detect my hdd on night time is that that is the time for electricity overusing. Am i right? if so, why is that my hard disk cannot still be detected even if i have my AVR (volage regulator)? why is that my CD-ROM drive is detected and my HDD is not(thou they're both disk drives). I've already checked all connections,including IDEs and power chords, and i think they're all properly fixed.

Please post me some solutions.
thank you so much!!! have a nice day!

sometimes your computer power supply is only a certain ammount of watts. It may not be detected if your HD is not getting sufficient power supply.. Try to hook it up to a power converter if you have one or another outlet within the room.. see if that helps.

I've already done those stuffs. It doesn't change anything. One thing i think is the solution right now is not to use the AVR with multiple power chords connected to it using the AVR with one . Just the system unit alone but it doesn't garantee me a hundred % effectivity.
